RF filtering protects the receivers against interfering signal and unwanted dirty RF, maintains continuous RF reception in Diversity operations. Multi-Band Digitally Tuned Semi-Board Band Antenna Distribution Module for sound bag, cart and trolley applications. The AD226-MB is a 2-IN and 2x6 OUT active antenna distribution system Digitally Tuned Variable Frequency with custom tuned bandwidths in the frequency range 470-832MHz offering the user selectable semi-broad band filtering options to suit any receiving systems available. The AD226-MB eliminates multiple receiver antennas and provides a tidy sound bag solution with improved RF performance. Advanced filtering design cleans up dirty RF within the operating bandwidth before feeding into the Diversity Receivers this is important in crowded radio frequency spectrum to protect the receivers from unwanted RF signals. The AD226-MB is a custom designed Antenna Distribution (AD) system offers the solution to the antenna and dc power distribution requirements for portable sound bag applications. Designed for where the weight and size matters without sacrificing on performance. The antenna inputs are BNC connectors which enables use of standard low loss RF coaxial extension cables, and the outputs are 2x6 mini-RF SMA connectors feeding the diversity receivers. In applications when remote active antenna powering is needed the AD offers switchable Active Antenna Powering with RED LEDs indicating power ON/OFF status, the Active Antenna Powering can be turned ON/OFF through the high visibility large display menu. The AD226-MB has an extremely high input signal handling capacity with exceptionally low noise figure and offers an outstanding inter-modulation performance when compared to other low power devices available. The tuning bandwidth is custom tuned with a semi broadband response to suit varying applications, the system RF gain is user adjustable in 1dB steps between +6dB to -10dB, the AD226-MB is compatible with full-digital, digital-hybrid and analogue radio microphone receivers available in the industry. The AD unit is externally powered between 10-18Vdc, the dc input connector is an industry standard 4-pin Hirose and there are 6xHirose dc output connectors available for powering auxiliary equipment. Each dc output port can be individually turned ON/OFF through the display menu. The inbuilt Voltmeter continuously displays dc input voltage status. Audio Wireless Antenna Distribution (AD) and Antenna Combiner (AC) and digitally tuned systems are now first choice among freelance sound engineers, hiring companies as well as major broadcasters for all wireless microphone applications. FEATURES: very wide band Digitally Tuned user selectable Band-Pass Filters one pair of antennae feeds up to four diversity receivers custom tuned band-pass filtering user-adjustable system gain active antenna powering soft ON/OFF switch for each individual Remote Antenna powering DC Distribution: 6 x Hirose dc outputs soft ON/OFF switch for each Hirose dc output industry standard connectors intuitive TFT display menu and LED indicators single power source solution master ON-OFF switch continuous system voltage monitoring (in-built DC Voltmeter) CNC machined aluminium custom design, lightweight and rugged fits neatly in any sound bag
